We're dividing 99455411 by 518 
The aim is to understand the frequency of 518 in 99455411.

On to step 1:
If we divide 9 by 518, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 518

On to step 2:
When dividing 99 by 518, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 518

Going ahead to step 3:
994 divided by 518 is 1 with a remainder of 476.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 518 from 994, we get 476.
Grab the next digit (5) from the dividend, add it to 476, then carry on: 4765 / 518

Advancing to step 4:
The number 518 fits into 4765 9 times, leaving a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 4662 away from 4765, we end up with 103.
Grab the next digit (5) from the dividend, add it to 103, then carry on: 1035 / 518

Let's proceed to step 5:
1035 divided by 518 is 1 with a remainder of 517.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtract 518 from 1035 to get 517.
Fetch the next digit (4) from the dividend, attach it to 517 and continue: 5174 / 518

Going ahead to step 6:
518 can be fit into 5174 9 times, resulting in a remainder of 512.
Use 9 as the next digit of our solution. 
Result so far: 1919.0
Deduct 4662 from 5174 and we're left with 512.
Append the next digit (1) from the dividend to 512 and continue with: 5121 / 518

Moving on to step 7:
When dividing 5121 by 518, we get 9 with a remainder of 459.
Write down 9 as next digit of the result. 
Result so far: 19199.0
If we take 4662 away from 5121, we end up with 459.
Include the next digit (1) from the dividend after 459, then repeat: 4591 / 518

Let's proceed to step 8:
4591 divided by 518 is 8 with a remainder of 447.
The number 8 becomes the next digit in our result. 
Result so far: 191998.0
Subtract 4144 from 4591 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 9:
518 can be fit into 4470 8 times, resulting in a remainder of 326.
Write down 8 as next digit of the result. 
Result so far: 191998.8
Subtract 4144 from 4470 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 10:
518 goes into 3260 6 times with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 191998.86
Deduct 3108 from 3260 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
518 can be fit into 1520 2 times, resulting in a remainder of 484.
Record the quotient 2 as the next digit in the result. 
Result so far: 191998.862
Deduct 1036 from 1520 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 12:
The number 518 fits into 4840 9 times, leaving a remainder of 178.
The next digit of our result is 9. 
Result so far: 191998.8629
If we subtract 4662 from 4840, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 13:
The number 518 fits into 1780 3 times, leaving a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 191998.86293
The remainder is 226 after subtracting 1554 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 14:
518 can be fit into 2260 4 times, resulting in a remainder of 188.
Record the quotient 4 as the next digit in the result. 
Result so far: 191998.862934
The remainder is 188 after subtracting 2072 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 15:
518 can be fit into 1880 3 times, resulting in a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 191998.8629343
Deduct 1554 from 1880 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 16:
If we divide 3260 by 518, we get 6 and a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 191998.86293436
Subtracting 3108 from 3260 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 191998.86293436 with a remaining 1.52e-07.
